ACPL-K342-560E – AVAGO

The ACPL-K342-560E is a single-channel, 5 kVrms isolation voltage gate drive optocoupler housed in an 8-pin small outline (SO) package. Manufactured by Avago Technologies (now Broadcom), this device utilizes an AlGaAs LED optically coupled to an integrated circuit with a power output stage. It is designed for driving IGBTs and MOSFETs in inverter and motor control applications. The integrated circuit provides features such as undervoltage lockout (UVLO) protection, preventing gate drive when the supply voltage is insufficient, and active Miller clamping, mitigating gate voltage spikes caused by Miller capacitance during switching. Propagation delay is typically in the sub-microsecond range, with minimal pulse width distortion. The “-560E” suffix denotes specific tape and reel packaging options and compliance with RoHS environmental standards. The device requires an external power supply for the output stage, typically in the range of 15-30V, depending on the gate charge requirements of the driven power transistor.
